ness to the sheets which it may be rolled over, but not to leak or drop the water when stationary resting on a non conducting substance. If properly supplied with, holes and carefully covered, the draft of water from the cylinder will be in exact proportion to the use, and a sufficient quantity of air will find its way into the cylinder through the covering to take the place of the water exhausted.

H, is a wooden roller with blotting paper covering revolving in the frame G, which may be passed over to remove any superfluous moisture.

I is a handle attached to the frame G G which serves to connect the cylinder E and roller H, so that they can be revolved together. l

From the foregoing Be it known that I, JOHN AUGUSTUS LYNCH, of Boston, county of Suffolk, and Commonwealth of Massachusetts, have ini vented a new and useful machine for dampening or wetting paper', &c., and particularly for dampening the sheets of letterbooks used in copying letters with a press; and I hereby declare that the following is a full and complete description of the construction and operation of the same, reference being' had to the annexed drawings, making a part of this specification, in which- Figure l, is a top view. tional view taken through the lines A, B, of Fig. l.

description it will be seen that by combining the wetting cylinder E and roller H with the handle I, connecting the two in the manner described, a new implement or machine is obtained, which performs the di'erent operations of wetting the sheet and absorbing the superfluous moisture, by taking hold of the handle and passing the apparatus once over the sheet.

implement or machine to be used in copying letters, &c., into copying books, in lieu of the usual process of first wetting the sheet by a brush or otherwise, and then absorbing the superfluous water with a sheet of blotting paper. My new apparatus for this purpose consists of a hollow perforated cylinder covered with cloth, and containing} water, and a second cylinder covered with Having thus described my improvement I shall state my claim as follows: I do not blotting paper, the two cylinders being connected byahandle, and revolving inaframe, claim a hollow perforated cylinder' through which water oozes as a similar device has whereby the sheet upon which the impression is to be made will be dampened by the been used for coating the inking roller of a but water cylinder and the superfluous moisture printing press, absorbed by the second cylinder atone oper- 1What I do claim as my invention and ation, by passing the machine once over the desire to have secured to me by Letters sheet.
